I know this may be in the wrong forum, but I have a question. I am working on a system for a video store. I have rentals and sales for videos. I have set the ID fields for rentals and sales to be autonumbers and increment by 1, but I would like to have an S in front of sales IDs and R in front of rental IDs at all times. It is kind of like a constant in all autonumber ID fields. I want the S and R to be in every ID field, but the number to change. Thanks.
